We prove that specific toric Landau-Ginzburg models for rank-1 Fano threefolds are families of Shioda-Inose surfaces, thereby explaining the observed modular properties of their associated regularized quantum differential equations. We conjecturally extend modularity to Fano varieties of any rank, and discuss this conjecture on toric examples.

We will begin by recalling the “down-to-earth” computation of the cohomol- ogy groups of a cyclic group with coefficients in Z from an earlier talk. Then we will show how the Lyndon / Hochschild - Serre spectral sequence can be used to obtain the known result.

Time permitting we will show how the same technique can be used to compute the cohomology groups of a dihedral group with coefficients in Z.

For toric manifolds, Lagrangian Floer theory of its torus fibers has deep relations to quantum cohomology, and mirror symmetry, where the mirror is described by LG superpotential W. We will give gentle introduction on this field, and discuss the extension to the case of toric orbifolds.

We give a proof of Cholak, Jockush, and Slaman that there is an ω-model of RT2 consisting entirely of low2 sets.

I will go through Chapter 2 of Tian's paper in detail, on Price's monotonicity formula, Uhlenbeck's curvature estimates, and singular Yang-Mills connections.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
